TIRE-FASTENING DEVICE.

' 5 State of Pennsylvania, have invented a new and useful Tire-Fastening Device, of which the following is a specification.

The invention relates to improvements in tire fastening devices.

In my prior application, filed on the 27th day of May, 1912, Serial No. 699,965, the operating hasp or arm for rotating the locking device to engage the head thereof with and disengage the same from the terminals of the split ring, is secured to the rim by the valve of the inner tube, thereby retaining the.

locking device in its engaged position. The present invention provides for the locking device an operating handle or arm adapted to be directly engaged with the rim of the Wheel to retain the locking device in engagement with the split ring.

The object of the present invention is to improve the construction of tire fastening devices, and to provide a simple, inexpensive and efficient tire fasteningdevice of strong and durable construction, designed for securing a pneumatic tire of the detachable type to the rim of an automobile or other vehicle wheel, and capable of'ready operation to enable a pneumatic tire to be easily and quickly removed from a wheel to repair or replace an inner tube,- or for any other purpose.

l/Vith these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims here- 46 to appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the clain may be resorted to without departin from the spirit or sacrificing any of the a vantages of the invention.

In theaccompanying drawing in which is illustrated the preferred embodiment of the invention, 1 designates a rim designed to be constructed of metal and secured by any suitable means to a wooden felly, .2. The felly 2 is connected with the outer ends of spokes 3 of an automobile or other vehicle wheel, which may be of any preferred c0 struction. The rim 1,- which is cylindrical, is provided at one of its side edges with an integral circumferential flange 4:, having a groove 5 in its inner face to receive the 1on tube or shoe engages a groove 9 in the inner side or face of a tire. engaging ring 4*, de tachably retained on the riin by a split ring 10 and cooperating with the fixed flange 4:- in securing the pneumatic tire to the rim. The pneumatic tire, which is of the clencher type, may be of any preferred construction, and it has an inner tube 11, constructed in the usual manner.

The split ring, which is resilient, .is constructed of suitable metal, and it is-seated in a circumferential.channel 15, formed in the rim adjacefrt to the side edge thereof and providingacircumferential rib or bead 12 at the inner, face of the rim arranged in spaced relation with the wooden felly to form a circumferential groove 13, as clearly illustrated in Fig. 5 of the drawing. The channel is segmental .-in cross section, and the inner periphery of the/split ring is gral lugs 16, extending across the circumferential channel and having straight radially arranged shoulders 17 and beveled faces 18, the beveled faces being located opposite the notches in the inrer periphery of the I split ring interlock the latter with the rim and prevent the split ring from creeping or moving longitudinally in the channel 15.

The notches are located adjacent to the ends' of the split ring, and the terminals of the latter have spaced inner portions 22 and are provided beyond the same with opposite recesses 23 to receive the T-shaped locking member.

The T-shaped locking member consists, of an oblong head and a rounded stem or pivot 25, journaled in the opening 19 of the rim and extending between the spaced terminal portions 22 of the split ring, the head of the T-shaped locking device being located opposite the recesses 23 and adapted to be carried into and out of the same by a rotary movement of the stem or pivot. The locking member is adapted to be rotated to arrange the head either transversely of the rim or longitudinally thereof, and when it is dis posed transversely of the rim, it is out of engagement with the recessed terminal portions of the split ring, and the latter is thereby released and may be readily sprung out of enga ement with the fixed lug 16 of the rim. 'W lien the head of the locking member extends longitudinally of the rim, it projects into the opposite recesses 23 and fits against the bottom walls thereof and holds .the split ring firmly in its interlocked rela the head of the T shaped fastening are rounded to enable the head to clear the end we lie of recesses 23. The continuous tire eugagin, 1g 4 is provided with an oblong recess 27 of a size to permit. the ring 4: to be over the head of the T-shaped catch in placing the tire engaging ring on and removing it from the rim.

The Tshapcd locking member is operated to turn its head into and outof engagement with the terminal recesses 23 of the split ring by means of an arm 28, fixed to the inner end the stem or pivot 25 and contructcd of resilient material and provided adjacent to its outer end with a bend 29 oftsetting its outer portion 30 slightly beyond the plane of the inner portion. The arm is located at the inner face of the rim, and

it'is adapted to be turned longitudinally of the same, and its terminal portion 30 en gages in the groove 13 at the inner side or behind the rib or head, as shown in Figs. 2 and 5, the arm being constructed of suitable material'to enable its terminal portion 30 to be readily sprung into and out of engagement with the said groove. The inner end of the operating arm may be connected to the stem or .pivot 25 in any suitable manner, and in the accompanying drawing the said stem or pivot is provided with a reduced squared portion 31, and the arm, which has a polygonal opening 32 to fit the squared portion, is retained thereon by a nut, 33 arranged on the threaded terminal 34 of the stem or pivot. The operating arm 28" when engaged with the groove 'of the .rimis ar ranged out of the way so'that it will not come in contact with a. stone .or other. obstruction in its use on an automobile or other vehicle Wheel. It is adapted to be readily sprung out of engagement withthe groove of the wheel when it is desired toturn the locking device.

' In the present application no, claim is made broadly to the split ring interlocked with the rim by the lugs and notches and provided with terminal recesses and having an entrance to the same at the inner periphery of the ring to permit the split ring to be passedover the head of the locking device, V

as this construction forms the subject-matter of certain claims of my prior copending application, filed May 27, 1912, Serial No. 699,965. Some of the claims of the present case, however, are generic to and are sumciently broad to cover the form of invention shown and described in my later copending application, filed on the 14th day of July, 1913, Serial No. 778,949, as thelatter application includes as a feature theresilient operating arm fixed to the rotary locking device and detachably interlocked with the rim of the wheel to maintain the locking device in engagement With the split ring. Instead of providing a continuous ring 4? for engaging one side of the outer tube or shoe, the split ring may, as illustrated'in Fig. 9 of the drawings'and as shown and described in my said copending application, be provided with a groove to receive the adjacent head of the tire. i
